Description

Technical Field

[0001] This invention relates to the field of foundation dynamic compaction reinforcement equipment, specifically to a dynamic compaction reinforcement device for liquefied foundations subjected to strong vibration. Background Technology

[0002] Liquefaction foundation refers to a type of foundation in which, under specific external forces, originally stable saturated loose soil experiences a sharp increase in pore water pressure and a rapid decrease or even approaches zero in effective stress, resulting in a significant loss of shear strength and exhibiting characteristics similar to liquid flow. Liquefaction foundation reinforcement utilizes hydraulic compactors, which are impact compaction devices that combine hydraulic drive with gravity and energy storage for pressurization. Their working principle is the same as that of dynamic compaction machines, both using the impact force and energy generated by the falling hammer to compact and reinforce the foundation.

[0003] Currently, relevant liquefaction foundation reinforcement technologies are typically mounted on loaders or excavators. The hydraulic system lifts the rammer to a set height and then releases it. The rammer accelerates its descent under the assistance of gravity and a hydraulic accumulator, impacting the grounding hammer head with a buffer pad. The kinetic energy is transmitted to the stratum in the form of a high-intensity pressure wave, causing the soil particles to reorganize and compact, thereby improving the foundation's bearing capacity and enhancing its resistance to liquefaction.

[0004] During the process of using hydraulic compactors to reinforce liquefied foundations, a large amount of soil accumulates on the compaction hammer. To remove this soil, the compaction hammer needs to be moved out of the compaction area and tilted for cleaning. However, hydraulic compactors do not have a soil collection function, which requires operators to manually transport the soil outside the compaction area to the compaction area to complete the backfilling and compaction work. Therefore, when it is necessary to backfill and compact the soil in layers in the compaction area, there is a technical problem that the soil accumulated during the compaction process cannot be directly utilized.

[0019] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 8 The device shown is a high-vibration liquefaction foundation dynamic compaction reinforcement device, which includes a loader 1, a fixed frame 2, a lifting frame 3, a compaction hammer 4 and a hydraulic lifting rod 5. The loader 1 provides power to the device and drives the device to move in position.

[0020] The fixed frame 2 is fixedly installed on one side of the loader 1, and the lifting frame 3 is slidably installed inside the fixed frame 2; the tamping hammer 4 is fixedly installed at the bottom of the lifting frame 3. A hydraulic lifting rod 5 is installed on each side of the fixed frame 2, and the two hydraulic lifting rods 5 move synchronously, with the loader 1 providing the driving force for the movement of the hydraulic lifting rods 5. One end of the hydraulic lifting rod 5 is installed on the fixed frame 2, and the other end is fixedly installed on the lifting frame 3. When the operator controls the hydraulic lifting rod 5 to raise or lower, it drives the lifting frame 3 to slide vertically along the fixed frame 2, thereby controlling the raising and lowering of the tamping hammer 4.

[0021] A waste soil recycling mechanism 6 is installed on the lifting frame 3. The waste soil recycling mechanism 6 includes a waste soil collection unit 60 and a crushing and storage unit 61. The waste soil collection unit 60 is located inside the lifting frame 3 and is used to collect waste soil and gravel generated during the compaction process.

[0022] The waste collection unit 60 includes a feed baffle 600, a conveying assembly 601, a fixed fin plate 602, a dual-shaft independent motor 603, an auxiliary drive assembly 604, and a collection container 605. Multiple feed baffles 600 are assembled to form a material-blocking space, and the feed baffles 600 are located on top of the compaction hammer 4. The fixed fin plate 602 is slidably disposed on the outside of the feed baffle 600. The bottom of the fixed fin plate 602 is fixedly connected to the top of the compaction hammer 4, and the top of the fixed fin plate 602 is fixedly disposed on the bottom of the lifting frame 3.

[0023] A dual-axis independent motor 603 is fixedly mounted on top of the conveying assembly 601 and is used to drive the conveying assembly 601 and the auxiliary drive assembly 604. The dual-axis independent motor 603 has two independent output shafts, but two motors can also be used to replace the dual-axis independent motor 603.

[0024] The material conveying assembly 601 is located within the material blocking space. The material conveying assembly 601 includes a material conveying housing 6010, a feeding screw 6011, and discharge pipes 6012. The material conveying housing 6010 is fixedly installed within the lifting frame 3. The feeding screw 6011 is rotatably installed within the material conveying housing 6010, and its top is poweredly connected to the first output end of a dual-shaft independent motor 603. Multiple discharge pipes 6012 are provided on the material conveying housing 6010, with one end of each discharge pipe located inside the housing. Waste soil and gravel conveyed upwards by the feeding screw 6011 are discharged outwards through the discharge pipes 6012. In this embodiment, four discharge pipes 6012 are provided.

[0025] The auxiliary drive component 604 is used to drive multiple feed baffles 600 to move synchronously.

[0026] The auxiliary drive assembly 604 includes a drive gear 6041, a driven gear 6042, a first drive shaft 6043, a second drive shaft 6044, a synchronous pulley 6045, a drive belt 6046, a forward threaded rod 6047, a first lifting plate 6048, a first nut 6049, a reverse threaded rod 6050, a second lifting plate 6051, and a second nut 6052.

[0027] One end of the first drive shaft 6043 is poweredly connected to the second output end of the dual-shaft independent motor 603 via a coupling; the drive gear 6041 is fixedly installed at the other end of the first drive shaft 6043. The driven gear 6042 is fixedly installed at one end of the second drive shaft 6044. The drive gear 6041 and the driven gear 6042 are meshed together. When the second output end of the dual-shaft independent motor 603 rotates, the first drive shaft 6043 rotates accordingly. Through the meshing of the drive gear 6041 and the driven gear 6042, the second drive shaft 6044 rotates.

[0028] A support plate 6053 is fixedly installed on the material conveying housing 6010, and the second drive shaft 6044 is rotatably mounted on the support plate 6053 via bearings.

[0029] The other end of the second drive shaft 6044 is fixedly connected to a synchronous pulley 6045; two adjacent synchronous pulleys 6045 are poweredly connected by a drive belt 6046. When the second drive shaft 6044 rotates, all synchronous pulleys 6045 rotate through the transmission between the synchronous pulleys 6045 and the drive belt 6046.

[0030] The forward threaded rod 6047 is fixedly installed at the bottom of the synchronous pulley 6045; a first lifting plate 6048 is fixedly installed at both ends of the top of each feed baffle 600, and a first nut 6049 is fixedly installed on the first lifting plate 6048, and the first nut 6049 is threadedly connected to the forward threaded rod 6047.

[0031] The collection container 605 is located at the bottom of the auxiliary drive assembly 604. An inclined concealment groove is formed on the upper surface of the tamping hammer 4, and the collection container 605 is located inside the inclined concealment groove. The inclined concealment groove provides a concealed space for the collection container 605, so as to avoid the collection container 605 interfering with the tamping work of the tamping hammer 4, while ensuring that the collection container 605 can smoothly receive the waste soil and gravel that slides off the feed baffle 600.

[0032] The reverse threaded rod 6050 is fixedly installed at the bottom of the forward threaded rod 6047; multiple second lifting plates 6051 are fixedly connected to the collection container 605; a second nut 6052 is fixedly installed on the second lifting plate 6051, and the second nut 6052 is threadedly connected to the reverse threaded rod 6050.

[0033] When it is necessary to reinforce a liquefied foundation with dynamic compaction, the operator first starts the loader 1 and moves it to the designated compaction area. Then, by controlling the extension and retraction of the hydraulic lifting rod 5, the lifting frame 3 and the compaction hammer 4 below it are adjusted to an appropriate height. At this time, the compaction hammer 4 is ready to carry out the compaction operation. During the compaction process, the compaction hammer 4 is subjected to strong vibration and impact force, which liquefies and compacts the foundation soil. During the compaction operation, The waste collection unit 60 starts working, and the soil will accumulate between the compaction hammer 4 and the fixed fin plate 602. As the soil accumulates, the dual-shaft independent motor 603 is started, driving the first transmission shaft 6043 to rotate, which in turn drives all the forward threaded rods 6047 to rotate synchronously through the second transmission shaft 6044. As the forward threaded rods 6047 rotate, the first nut 6049 drives the first lifting plate 6048 and the feed baffle 600 to slide up and down along the lifting frame 3, and the reverse threaded rod 6050 rotates with the rotation of the forward threaded rods 6047, controlling the second lifting plate 6051 to descend, further lowering the collection container 605 into the inclined concealment trough. At this time, with the vibration of the compaction hammer 4, the waste soil and gravel enter the collection container 605 from the opening of the feed baffle 600.

[0034] As the compaction work continues, the amount of waste soil and gravel in the collection container 605 gradually increases. When the preset capacity is reached, the reverse drive rotates the forward threaded rod 6047, causing the feed baffle 600 to descend and return to its original position. The reverse threaded rod 6050 also rotates in the opposite direction, removing the collection container 605 from the inclined concealed groove 2106 and raising it below the conveying shell 6010 to dock with it. During the accumulation process, the other shaft of the dual-shaft independent motor 603 is started, which drives the feeding screw 6011 to rotate, and inputs the waste soil or gravel into the conveying shell 6010. This process is repeated to collect the waste soil and gravel. When the waste soil and gravel rise to the top of the conveying shell 6010, they are discharged from the discharge pipe 6012.

[0035] The crushing and storage unit 61 is located outside the lifting frame 3. The crushing and storage unit 61 is used to store and crush the waste soil and gravel collected by the waste soil collection unit 60, and process them into granular materials for foundation reinforcement.

[0036] The crushing and storage unit 61 includes a processing shell 610, a fixed hanging plate 611, a crushing roller 612, an outer shaft 613, an inner shaft 614, a first bevel gear 615, a second bevel gear 616, a crushing drive motor 617, a discharge pipe 618, and a control valve 619.

[0037] A fixed hanging plate 611 is fixedly installed on the top of the processing housing 610, and the fixed hanging plate 611 is provided with a rectangular opening. A material-gathering baffle 622 is provided inside the processing housing 610, which is used to gather waste soil and gravel inward.

[0038] Roller 612 is fixedly installed on both the outer shaft 613 and the inner shaft 614. The roller 612 has teeth on its surface. When the two rollers 612 rotate relative to each other, the teeth crush the waste soil and gravel.

[0039] A crushing drive motor 617 is fixedly installed inside the processing housing 610. The crushing drive motor 617 drives the outer shaft 613 and the inner shaft 614 to rotate. Specifically, the output end of the crushing drive motor 617 is fixedly connected to the outer shaft 613 via a coupling. A first spur gear 620 is fixedly installed on the outer shaft 613, and a second spur gear 621 is fixedly installed on the inner shaft 614. The first spur gear 620 and the second spur gear 621 are meshed together. When the crushing drive motor 617 drives the outer shaft 613 to rotate, the inner shaft 614 is driven to rotate through the meshing transmission of the first spur gear 620 and the second spur gear 621.

[0040] A first bevel gear 615 and a second bevel gear 616 are fixedly installed at both ends of the outer shaft 613, and a first bevel gear 615 and a second bevel gear 616 are also fixedly installed at both ends of the inner shaft 614, with the corresponding first bevel gears 615 and second bevel gears 616 meshing together. Through the meshing transmission of the first bevel gears 615 and second bevel gears 616, all outer shafts 613 and inner shafts 614 rotate.

[0041] There are four outer shafts 613 and four inner shafts 614. The four outer shafts 613 are arranged in a rectangular shape, and the four inner shafts 614 are located inside the four outer shafts 613.

[0042] Multiple discharge pipes 618 are provided at the bottom of the processing shell 610, and control valves 619 are installed inside the discharge pipes 618. When the control valves 619 are opened, waste soil and crushed stone particles can flow out from the discharge pipes 618, which facilitates subsequent operations by construction personnel.

[0043] After the soil and gravel are discharged from the discharge pipe 6012, they first pass through the compaction roller 612. Before crushing, the crushing drive motor 617 is started, driving the outer shaft 613 to rotate. The meshing transmission of the first spur gear 620 and the second spur gear 621 drives the inner shaft 614 to rotate synchronously. At this time, the outer shaft 613 and the inner shaft 614 drive the compaction roller 612 to begin crushing the soil and gravel, converting them into granular materials that can be used for foundation reinforcement. As the amount of granular material gradually increases, after the processing shell 610 is full, the control valve 619 can be opened to allow the granular material to be discharged from the discharge pipe 618. The material is then guided to the compaction zone for layered backfilling through external pipelines.

[0044] The above embodiments are merely illustrative of the concept and implementation of the present invention and are not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
